Hi,
I have sent a previous message showing something that I think is a bug
(or maybe a misuse, but...).
I worked on the example sent to have it simplified: now it is almost
half of the lines of code and the structures are more simple... but
still showing the wrong behaviour.
Briefly, we construct different MPI_datatype and nests them into a final
type which is a:
{MPI_LONG,{{MPI_LONG,MPI_CHAR}*2}
Here is the output from OpenMPI 1.6.3:
Rank 0 send this:
i: 0 => {{0},{{3,%},{7,5}}}
i: 1 => {{1},{{3,%},{7,5}}}
i: 2 => {{2},{{3,%},{7,5}}}
i: 3 => {{3},{{3,%},{7,5}}}
i: 4 => {{4},{{3,%},{7,5}}}
i: 5 => {{5},{{3,%},{7,5}}}
MPI_Recv returned success and everything in MPI_Status is correct after
receive.
Rank 1 received this:
i: 0 => {{0},{{3,%},{-999,$}}} *** ERROR ****
i: 1 => {{1},{{3,%},{-999,$}}} *** ERROR ****
i: 2 => {{2},{{3,%},{-999,$}}} *** ERROR ****
i: 3 => {{3},{{3,%},{-999,$}}} *** ERROR ****
i: 4 => {{4},{{3,%},{-999,$}}} *** ERROR ****
i: 5 => {{5},{{3,%},{-999,$}}} *** ERROR ****
Here is the expected output, obtained with mpich-3.0.3:
Rank 0 send this:
i: 0 => {{0},{{3,%},{7,5}}}
i: 1 => {{1},{{3,%},{7,5}}}
i: 2 => {{2},{{3,%},{7,5}}}
i: 3 => {{3},{{3,%},{7,5}}}
i: 4 => {{4},{{3,%},{7,5}}}
i: 5 => {{5},{{3,%},{7,5}}}
MPI_Recv returned success and everything in MPI_Status is correct after
receive.

Is it related to the bug reported here:
